[Healeys] BN1 mufflers - steel or stainless

[Kees Oudesluijs]

Stainless steel is the way to go.

Sound is created by the manufacturer, not the material any more. Most 
after market systems are designed to produce a louder and "deeper" sound 
than original, not for BHP´s. The pattern is usually more or less 
original, however in the US many systems are cobbled together on 
European cars, at least that is what we see in Europe when these cars 
are being reimported from the USA.

As the cars are not driven regularly, corrosion is an issue thus mild 
steel exhaust may not last very long especially the rear silencer as 
acid condensed water rots it out from the inside, especially when they 
are straight through filled with glass wool.

Stainless steel silencers are usually straight through and filled with 
glass wool. In time this glass wool gets sooted up or is blown out of 
the box leaving you with a very loud car. This would be the same in a 
mild steel system, however the silencer would have rotted away long 
before it gets that far.
